The taxonomic status of strain YIM 78110T was confirmed by a polyphasic approach. 16S rRNA gene sequence analysis indicated that strain YIM 78110T belongs to the genus Cecembia, displaying 96.8 % and 94.7 % sequence similarity with the two most closely related type strains, Cecembia calidifontis RQ-33T and Cecembia lonarensis LW9T, respectively. The low value of DNA–DNA hybridization (52.3 ± 2.3 %) between strain YIM 78110T and its closest neighbour, Cecembia calidifontis RQ-33T, indicated that this new isolate represented a different genomic species in the genus Cecembia. The temperature for growth ranged from 30 to 50 °C. The pH for growth ranged from pH 4.0 to 10.0, with NaCl tolerance of 0.5–6.0 % (w/v). The predominant menaquinone of strain YIM 78110T was MK-7 and the major polar lipid was phosphatidylethanolamine. The major fatty acids were iso-C15:0 and C15:0. The DNA G+C content was 47.1 mol%. On the basis of physiological, biochemical and phylogenetic analyses, it is proposed that strain YIM 78110T represents a novel species of the genus Cecembia, for which the name Cecembia rubra sp. nov. is proposed. The type strain is YIM 78110T ( = CCTCC AB2013287T = DSM 28057T). %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.000227
